The Washington Nationals' 2026 starting rotation is shaping up to be one of the most intriguing—and potentially controversial—lineups in recent memory. But here's where it gets controversial: Will the Nats really part ways with their ace, MacKenzie Gore, and if so, what does that mean for the team's future? This question has dominated the offseason, and the ripple effects will be felt across the organization. While the Nationals recently bolstered their rotation by signing lefty Foster Griffin, the bigger question remains: How will they fill the void left by Gore's potential departure? And this is the part most people miss—the Nats' rotation isn't just about replacing one star; it's about rebuilding a foundation for success.
Let’s break it down. If Gore is traded—and MLB experts widely believe he will be—the Nats' rotation loses its cornerstone. Gore’s production isn’t just good; it’s irreplaceable with the current roster. The team’s front office, led by Paul Toboni, will need to strike gold with the trade return, ideally landing another starting pitcher who can step into a leadership role. But even then, it’s a gamble.
Now, let’s talk about the pitchers who are already in the mix. Jake Irvin and Mitchell Parker are two names that spark debate. Both struggled immensely in the 2025 season, with Irvin posting a 5.80 ERA and Parker not far behind at 5.68. Their performances were eerily similar, save for their handedness. The Nats can’t afford to cut ties with either just yet—their depth is too thin. Adding Giff McGarry in the Rule-5 Draft helps, but he’s not a magic fix. The team needs more, and fast.
Then there’s Cade Cavalli, the wildcard. With just 11 career MLB starts under his belt, Cavalli remains an enigma. He showed flashes of brilliance in 2025, but at 27 years old in 2026, it’s now or never. Will he sink or swim? The Nats’ new coaching staff could be the key to unlocking his potential, but it’s a risky bet. Seeing him make 25+ starts in 2026 would be a career-defining moment, but it’s far from guaranteed.
Speculating on the 2026 rotation in December feels like reading tea leaves, but let’s try anyway. Without Gore, the Nats’ options include Brad Lord, Cade Cavalli, Jake Irvin, Mitchell Parker, Josiah Gray, and Griff McGarry. DJ Herz and Trevor Williams will still be sidelined, leaving the rotation thin. Irvin and Parker’s inclusion feels like a stopgap at best, which means the Nats must act—and act boldly. The return from a Gore trade could help, but free agency is where they’ll need to make a splash. Zach Gallen, for instance, is a free agent who fits the bill: reliable, affordable, and with a track record of durability. His 2025 season was a blip, but his previous ERAs suggest he’s a solid bounce-back candidate.
Foster Griffin is a step in the right direction, but he’s not the savior this rotation needs. The Nationals must add more talent, plain and simple. Without Gore, they lack a true number-one starter, and their prospects—Travis Sykora, Jarlin Susana, and Alex Clemmey—are years away from the majors. Paul Toboni may need to look outside the organization to find the missing pieces.
Here’s the burning question: Can the Nats rebuild their rotation without sacrificing their long-term goals? And if they trade Gore, will the return be enough to justify the loss? Let us know your thoughts in the comments—this is one debate that’s far from over.
